Jake Shields finally reveals what he failed UFC 150 drug test for

Remember back in 2012 when Jake Shields failed a post-fight drug test after beating Ed Herman at UFC 150? The former Strikeforce middleweight champion was returning to the 185 lb. division for the Herman bout after initially entering the UFC as a welterweight . The bout took place in Colorado, and the state's commission never actually released what Shields had failed for. Shields wouldn't say either. Until now.

The current WSOF fighter had to call into a Nevada State Athletic Commission meeting to get licensed for his bout against Brian Foster this Saturday. This is only required of fighters over 35 years of age, which is why Anderson Silva was on the docket today as well (spoiler - he got licensed). Anyway, the commission decided to ask Shields what he failed for and he admitted it was a diuretic, used to cut weight. But he was vague about the details.

"I don’t really know too much about it, to be honest. Obviously it was a mistake, and I served my suspension.

...

"I learned from my mistakes. I definitely don’t want to go through what I went through before."

He stated that he got the substance via "someone I know through another fighter". He was also asked about his part in the infamous Strikeforce Nashville brawl in 2010 that involved Jason "Mayhem" Miller and a few members of Shields' team. He said that he would never make that mistake again.

Shields was granted a conditional license, but still has to submit paperwork showing a clean MRI and a test for hepatitis B.
